       5. The unit according to  claim 2 , wherein the connection unit has a ratio of a diameter perpendicular to a length direction to a length ranging from 1:4 to 1:10. 
     
     
       6. The unit according to  claim 2 , wherein the connection section includes a bundle of a plurality of metals. 
     
     
       7. A heat exchanger unit comprising:
 a plurality of heat exchangers, each of the heat exchangers includes magnetic particles and a refrigerant therein; and 
 a connection section provided between the heat exchangers to connect the heat exchangers, the connection section including a solid-core member, a porous body, or a combined substance of the solid-core member and the porous body, the connection section being coated by a heat-insulating layer, 
 wherein the connection section invades partially into an inside of the heat exchangers connected thereto. 
 
     
     
       8. The unit according to  claim 7 , wherein the solid-core member, the porous body or the combined substance of the solid-core member and the porous body is made of a metal. 
     
     
       9. The unit according to  claim 8 , wherein the metal is made of copper or a copper alloy whose main component is copper. 
     
     
       10. The unit according to  claim 7 , wherein each of the heat exchangers includes two openings, the openings are disposed opposite each other, and a length of the connection section is equal to or shorter than a distance between the two openings of one of the heat exchangers connected thereto. 
     
     
       11. The unit according to  claim 8 , wherein the connection unit has a ratio of a diameter perpendicular to a length direction to a length ranging from 1:4 to 1:10. 
     
     
       12. The unit according to  claim 8 , wherein the connection section includes a bundle of a plurality of metals. 
     
     
       13. A thermal cycling unit comprising:
 a heat exchanger unit having a plurality of heat exchangers, each of the heat exchangers includes magnetic particles therein, and a connection section provided between the heat exchangers to connect the heat exchangers, the connection section includes a solid-core member, a porous body, or a combined substance of the solid-core member and the porous body, the connection section being coated by a heat-insulating layer;
